The PRIMA is its first word in the present tense — and a deliberate one. Co-owners Yvan Ketterer and Leopoldo Celi have resisted the easy re-edition, instead taking the brand's 1928 jump-hour as a starting point and building a form watch around it that feels closer to Streamline Moderne than to costume nostalgia. The reason to take it seriously is the NHS01. A shaped, hand-wound caliber developed specifically for this case, it carries both the Geneva Seal and ISO 3159 chronometer certification — a pairing no independent has ever managed at launch — and hides its construction beautifully, with bridge screws relocated to the flanks and rhodium-plated bridges that read as a single uninterrupted surface. The display is pure regulator logic: a jumping digital hour, a rotating minute disc, running seconds at six, each hour change marked by a soft mechanical tack from a gong soldered into the case. At 7.9mm it wears as a genuine dress watch. Among the recent wave of jump-hours, it is the rare one with the provenance and the chronometry to back the concept.
